The K5 touchscreen hardware can only track two touch points, not three. And because the two points can swap X or Y coordinates when crossing a horizontal or vertical axis, unless velocity tracking is added to compensate for that bug, you can only use the bounding box diagonal to control pinch and zoom, or to do pinch and stretch gestures. Touchscreen rotation is tricky and/or glitchy.

Thanks Geekmaster! Well I guess that's out of the question..... I guess it's back to trying to figure out how to re-enable pinch-zoom...
